History Manga / ShionNoOu

* AbusiveParents: Saitou Ayumi's father is emotionally abusive; he even blames Ayumi for his birth making his mother ill.

* HotBlooded: Many of the ''kishi'' can get ''very'' enthusiastic about the game. The animation style used when the players make their moves further emphasizes this.

* ArtShift: In the anime, whenever Shion recovers a memory of the night when her parents were murdered, the art style becomes sketchy and much DarkerAndEdgier.

* UnsettlingGenderReveal: [[spoiler:Saito Ayumi]], though the story doesn't hide it from the viewers for long. Satoru [[spoiler:''intentionally'' drops this particular Bridget on Nikaido Saori]] for what seemed like no reason at all, though it may just be part of his [[spoiler:BatmanGambit to find out who killed the Ishiwataris]].

** [[spoiler:Satoru]] also counts.

* LeaveNoWitnesses: In an interesting and complex variant, the killer threatened Shion into silence (to the extent that she became ''mute'') and intentionally used [[spoiler:Kazumi, who had a very weak heart and died as a result of finding out that she was an accomplice (albeit unintentionally), when Satoru was away]], [[MurderByInaction leaving her to die]] [[MakeItLookLikeAnAccident without even needing alibi]].

* {{Bishonen}}: Ayumi-kun qualifies. There are also several examples of {{Biseinen}}: Hani Makoto, Hani Satoru, and Hisatani.

* AffablyEvil: The BigBad and murderer of [[spoiler: Shion's parents and Kazumi, Hani Makoto]], seeing as his methods and philosophy on a single topic are what make him evil.

* AffablyEvil: The BigBad and murderer of [[spoiler: Shion's parents and Kazumi, Hani Makoto]], seeing as his methods are the evil part.

* AffablyEvil: The BigBad and murderer of [[spoiler: Shion's parents and Kazumi, Hani Makoto]].

* ManipulativeBastard: The motive and modus operandi of the killer, [[spoiler:Hani Makoto]], really nails this one: [[spoiler: he murdered Shion's parents, played a game with her then and there, threatened her into silence, and later continually separated her from Ayumi (thus isolating her) to develop Shion into a better shogi player (according to his philosophy)]].

* BadBoss: As [[spoiler:Ayumi]]'s master, [[spoiler:Hani Mokoto]] shows this, largely by being a {{Jerkass}} and frequently [[KickTheDog maltreating]] his apprentice. Later, this turns out to be partially a case of being a convoluted ManipulativeBastard, but it could easily be both since he deliberately choses methods involving [[KickTheDog kicking the dog]]... a lot.

* ShownTheirWork: The writer is a professional shogi player, and it really shows.

* LeaveNoWitnesses: In an interesting and complex variant, the killer threatened Shion into silence (to the extent that she became ''mute'') and intentionally used [[spoiler:Kazumi, who had a very weak heart and died as a result of finding out that she was an accomplice (albeit unintentionally), when Satoru was away]], [[MurderByInaction leaving her to die]] [[MakeItLookLikeAnAccident without lifting a finger]].

* LeaveNoWitnesses: In an interesting and complex variant, the killer threatened Shion into silence (to the extent that she became ''mute'') and intentionally used [[spoiler:Kazumi, who had a very weak heart and died as a result of finding out that she was an accomplice (albeit unintentional), when Satoru was away]], [[MurderByInaction leaving her to die]] [[MakeItLookLikeAnAccident without lifting a finger]].

* BloodSplatteredInnocents: Although this wasn't true of the actual event (to despite the state of the apartment), all of Shion's dreams about her parents' murder have this to some degree.

* Blood-SplattedInnocents: Although this wasn't true of the actual event (to despite the state of the apartment), all of Shion's dreams about her parents' murder have this to some degree.

* BloodSplattedInnocents: Although this wasn't true of the actual event (to despite the state of the apartment), all of Shion's dreams about her parents' murder have this to some degree.

* LaserGuidedAmnesia: Shion can only remember bits and pieces about the murder of her parents that she witnessed.

* CuteMute: The eponymous Shion, who lost the ability to speak after witnessing the murder of her parents.

* ArtShift: Whenever Shion recovers a memory of the night when her parents were murdered, the art style becomes sketchy and much DarkerAndEdgier.

* BloodSplattedInnocents: Although this wasn't true of the actual event, all of Shion's dreams about her parents' murder have this to some degree.

* BreakTheCutie: All three main characters, at least once. Shion, especially, since the murderer intentionally murdered her parents in front of her and "sealed off" her voice.
